Started the rudder, trimmed final drilled and resized the R915 stiffeners
to skin left and right sides.
NOTE: When matching the R915 stiffeners to the skin, start
on the right side using an uncut R915 stiffener and match the hole
pattern to the skin. Notice the right side 90 degree angle is facing
down. After cutting the right side R915 stiffener to size
the remaining portion of the R915 stiffener will fit on the left rudder
skin with the 90 degree angle facing up. The end result
should be a box configuration. Look close at this pic and see the direction
of the angle bends on the R915 stiffeners.
